How much does central air installation cost with existing ductwork?

Central air installation with existing ductwork at Roy’s is priced after an in‑home assessment, and current promotions may offer payments as low as $92 per month for new A/C installation. The biggest cost driver is matching the right system size and efficiency to your home so it cools evenly without wasting energy.

Our team regularly installs central air in the Buffalo area, and we verify that your existing ducts, return air, and controls support the new system’s performance.

Your final price typically depends on:

  • System tonnage and efficiency rating (how much cooling and how efficient)
  • Condition of existing ductwork and need for any adjustments
  • Refrigerant line‑set routing and outdoor unit placement
  • Optional add‑ons like smart thermostat integration

Final pricing is confirmed after an on‑site inspection so the quote reflects your exact home and goals.
